1 Claim.

The present invention relates to devices for holding razor blades while sharpening the same; and its object is, generally, to provide a device of that character improved in respects hereinafter appearing; and particularly, to provide an improved handle for such a device; and further, to provide improved constructions of the members of such a device; and further, to provide such a device having means for flexing the razor blade held thereby into different sharpening positions.

These and any other and more specific objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the device particularly described in the body of this specification and illustrated by the accompany' ing drawing, in which Figure 1 is a top plan view of a device for holding razor blades while sharpening the same, showing such a. blade held thereby;

Figure 2 is a side view thereof;

Figure 3 is an end view of the same;

Figure 4 is a side view of the handle member of the device;

Figure 5 is a side view of the base member thereof;

Figure 6 is a view of a flat blank from which the base member may be formed;

Figure 7 is a transverse sectional view of the base member taken on a plane corresponding to line 7-7 of Figure 6,;

Figure 8 is a transverse sectional view of the base member taken on a plane corresponding to line 88 of Figure 6;

Figure 9 is an end View (enlarged) of the device with a razor blade held thereby and a hone on which the same is being sharpened;

Figures 10 and 11 are views similar to Figure 9, showing the device as held by the operator; and

Figures 12 and 13 are transverse sectional views (much enlarged) of a portion of the razor blade in difi'erent flexed positions while being sharpened.

The device illustrated by the drawing for holding a safety razor blade while sharpening the same, comprises the separable base member 1 and handle member 2. The base member has a pair of posts 3 which extend upwardly through holes 4 in the middle portion 5 of the handle member and through the usual registering holes of the razor blade 6, so that the blade is held between said members against edgewise movement. The under surface '7 of the base member is curved convexly downwardly in trans- I verse vertical planes so that the device may be rocked and slid back and forth on a suitable sharpening agent as the hone 8, in the sharpening operation as indicated particularly in Figures 10 and 11. The handle member 2 is desirably made of sheet metal bent to form the middle portion 5 and opposite portions 9 extending upwardly and then inwardly-downwardly, being thus formed for engagement by the fingers of the operator as illustrated in Figures 10 and 11, said opposite portions being desirably provided with outward extensions 10 to facilitate such holding engagement. An upwardly extending handle with a depression in its top is thus provided.

The base member 1 is desirably made of a flat sheet metal blank 11 shown in Figure 6 out to form side portions 12 connected by transverse end portions 13, said base member being formed by pressing these end portions 13 upwardly to provide the spaced hollow posts 3, thus bringing the side portions 12 together with their adjacent edges 17 into approximate contact, and bending said side portions into upwardly concave, downwardly convex, shape to form said rock bearing for the device.

The middle portion 5 of the handle member 2, either being somewhat concave on its under side as indicated in Figure 9 or (equivalently thereto) being flexible so as to assume that shape, it will be seen that downward pressure on its handle portions 9 will cause the flexible razor blade to be flexed to a like shape by means of the pair of lateral edges 18 of the handle member and the pair of lateral edges 15 of the base member engaging opposite sides of the blade, one pair being spaced outwardly fromthe other pair in the devices lateral direction. Thus, in sliding and rocking the device on the hone the blade may be given a greater or less degree of flexure depending on the degree of such pressure.

In Figure 13 such pressure and consequent flexure is greater so that the blade is ground and sharpened at its extreme edge 16; while in Figure 12 such pressure and consequent flexure is less so that the blade is ground rearwardly from its edge.

This device may thus be operated similarly to, and with like effect as, a razor of original type may be sharpened.

The handle portions 9 are so formed and relatively disposed that the fingers of the operator may readily grasp the same and effect so as to bring the side portions together with their inner edges adjacent and so curved as to form their under surfaces downwardly convex for providing an under surface for the device adapted to rock and slide on a sharpening agent and said end portions being bent upwardly to provide a pair of spaced hollow posts adapted to be inserted into correspondingly spaced holes in the blade, and the other one of said v members having Iholes adapted to receive the posts in the held position of the blade between said members.
